Video Visualization for Snooker Skill Training

Abstract

We present a feasibility study on using video visualization to aid snooker skill training. By involving the coaches and players in the loop of intelligent reasoning, our approach addresses the difficulties of automated semantic reasoning, while benefiting from mature video processing techniques. This work was conducted in conjunction with a snooker club and a sports scientist. In particular, we utilized the principal design of the VideoPerpetuoGram (VPG) to convey spatiotemporal information to the viewers through static visualization, removing the burden of repeated video viewing. We extended the VPG design to accommodate the need for depicting multiple video streams and respective temporal attribute fields, including silhouette extrusion, spatial attributes, and non-spatial attributes. Our results and evaluation have shown that video visualization can provide snooker coaching with visually quantifiable and comparable summary records, and is thus a cost-effective means for assessing skill levels and monitoring progress objectively and consistently.

La existencia de necesidades de información y comportamiento informativo en los entrenadores en deportes de combate

“…Por su parte Guy (1979) confirma que los investigadores utilizan las fotografías y videos mientras que los entrenadores con frecuencia los frecuenta para obtener información, aunque no son sus principales fuentes para obtener información. Un dato curioso es el que se tiene del video que es el de mayor uso y concuerda con Wilson (2008) asimismo con Höferlin et al, (2010). Probablemente el deporte al aprenderse de forma práctica y al visualizar las técnicas de golpeo ayuda sin duda a mejorar los movimientos tanto de los entrenadores como del atleta.…”

“…El deporte se encuentra rodeada de especialistas como médi-cos, nutriólogos, psicólogos, masoterapeutas, fisioterapeutas, entre otros, los cuales están allí para practicar más inteligentemente las actividades deportivas mismos que pueden brindar información al entrenador (Lévesque,1991). Por su parte, Wilson (2008) y Höferlin et al, (2010 mencionan que el video ha sido utilizado por el entrenador para observar el desempeño de los atletas y con esto hacer ajustes en sus técni-cas y habilidades.…”

Augmented reality system to assist inexperienced pool players

“…However, our system works in real time and in real conditions, whereas systems like Refs. [2,4,22] work with video (or video streams) taken from pool or snooker championships, with very stable and controlled conditions (lighting, player positions, etc. ), or expect a controlled environment because of the use of robots [5][6][7].…”

“…Unlike those systems, e.g., Ref. [2], the application proposed in this paper is an AR tool that enhances on-the-fly the perception of what the player is currently doing by projecting a calculated trajectory onto the table.…”

“…Many of them are focused on analysing video footage mostly to give a 3D representation of the game [2][3][4]. Unlike those systems, e.g., Ref.…”
